    Hello All,
    I bought a used Note 4 with following specs:
    - KK 4.4.4, N910F (F-Firmware) , GERMAN language

    I decided to flash CM 12.1 and lost my IMEI and Baseband; unfortunately made no efs-backup or any backup .
    CM 12.1 runs stable, but no signal , no telephony...; with various apps (CPU-Z etc.) I checked all device details:
    - Modell: N910F , but N910P (P-modell) as bootloader....
    Trying to install stock F-Firmware again, it failed; I could only install stock P-Firmware (US Sprint)....there are differences in trltespr, trlte, trltexx...???

    Please help me, how can I get back IMEI, baseband and more how can I get back 1st F-Firmware with GERMAN language (I bought it with KK 4.4.4, N910F ( F-Firmware) , GERMAN language)!
    The last 2-3 days and nights I installed P-Firmware, but only with a few english/south-american languages; with P-Firmware IMEI & baseband are 100% ok...but no german language and LTE here....!
    Please help, how can I get back to 1st version....?
    Thanks a lot

    Happened to my old s4 when I flashed google play edition rom. Fortunately some one had put a baseband imei package together and was able to flash that on top

    Hi Joe,
    thank you for reply...
    I tried several times to flash F-Firmware StockRom...result is, that I got no signal, no IMEI, no baseband.
    Do you have additional instructions? where to find "baseband imei package"... which one?
    Thanx a lot..

    Best guess would be to ask on XDA forums. Sorry can't be of more help

    Hello Bosbouer,
    thank you for link....
    Are you sure that I will have IMEI and baseband? Because , last week I installed F-Firmware [N910FXXU1ANK4_N910FOXA1ANK4_N910FXXU1ANK4_HOME.tar.md5].. installation ok, but no IMEI, no baseband, no signal....!
    Everytime I install F-Firmware this happens; when installing P-Firmware its OK (but no german or eurapoean languages).
    Thank you for additional info...
